7 Claims.

This invention relates to expansible hair curling device.

The general object of the invention is to provide a hair curling device wherein the ends of a strand of hair are secured to and wrapped about a hair curling device after which the device is expanded to place the hair under tension so that a better curl is secured.

An additional object of the invention is to provide a hair curling device including a pair of relatively slidable members having means thereon for causing the members to separate.

A further object'of the invention is to provide a hair curling device including means for engaging the ends of a strand of hairand having clamping means thereon for producing tension in the hair after it is clamped in place.

Other objects and advantages of my invention will be apparent from the following description taken in connection with the accompanying drawing, wherein:

Fig. 1 is a longitudinal sectional view of the upper or relative stationary part of the hair curler.

Fig. 2 is a longitudinal sectional view of the ower or movable part-of'the curler.

Fig. 3 is a longitudinal "sectional view with parts in elevation showing the assembled curler.

Fig. 4 is a plan View of the curler.

Fig. 5 is a view similar to Fig. 3 showing the curler expanded.

Fig. 6 is a section taken online and Fig. 7 is a, section takenon line 1 of Fig. 3.

Referring to the drawing by reference characters, I have shown my invention as embodied air curling device which is indicated generally at In. As shown the device includes .a body member H which is adapted to engage the head of the person whose hair is 6-6 of Fig. 3,

flange l2 from which a boss I3 projects. The boss I 3 includes a cylindrical hole 13" which is threaded as at 14. Th includes an end 55 which has an axial hole It The intermediate portion I! of the cess "1'9 which aligns with the holes [3' and I 6. Mounted on the body I show a hair clamping body member 29 which includes an end 2| slidable along the inner surface of the end l2 and includes the end portion .22 slidable along the inner surface of the-end [5.

The end 2| is slotted as at 23 to receive the threaded tip 24 of an operating member 25. The member 2a includes a semi-cylindrical recess 26 in which theoperating member 25 is arranged. The recess 25 is in substantial alignment with the recess [9 previously mentioned. The operatdy l I includes a front end' e rear end of the body ll ing member 25 includes a pair of cam members 2'! and '28 with the cam partly in a recess 29 in the the cam member 28 partly 5 30 in the member -II. Th adapted toengage a cam su member 21 disposed member I I and with disposed 'in a recess e cam member '21 is rface 3| and the cam member 28 is adapted toengage a cam surface 32,

The flange 36 is also provided with a plurality of holes 40 which are shown as three in num- 35 ber, and in each of th 7 4i. Eachof the fingers 4-] tion 42 arranged in the as also includes an int has an aperture 45 40 boss l3. The fingers irial and include 100 which e holes I arrange a finger includes an end porsociated hole 40 and ermediate portion 44 which is mounted on the are made of resilient matep portions 46 and 4'! which wardly from the slot 4!] so that the clamping finger may be entirely removed.

.In use the clamping fingers 4| and the end of the strand of hair are removed which is to be curled is inserted under the clamping arm and at H released thus holding the ed winding the hair and 2B. When the ed on the body meml are mounted in 33 is rotatedcallsing 8 to engage their re causing a separating movement between the members II and 20. This stretches the hair and it is allowed to remain in this position until it is thoroughly dried after which the curler is removed.

From the foregoing description it will be apparent that I have invented a novel hair curler which can be economically manufactured and which is highly eflicient for its intended purpose.

Having thus described my invention, I claim:
